Peanut Butter Oatmeal M&M Cookies

Happy Friday!  I was in the mood for baking cookies.  When am I not?  My husband and I LOVE cookies, whether it’s baking them or eating them (but mostly eating them).  No wonder why Cookie Monster was my favorite Sesame Street character when I was a kid.     😉

These Peanut Butter Oatmeal M&M cookies are packed with peanut butter flavor.  It makes sense since that’s why it’s part of the name.  These are perfect for all those peanut butter fans out there!


Peanut Butter Oatmeal M&M Cookies Recipe
(Makes about 34 cookies)


  • 1 cup all-purpose flour
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 and 1/2 cups quick cooking oats
  • 3/4 cup (equivalent to 1 and 1/2 sticks) butter
  • 1/2 cup white sugar
  • 1 cup brown sugar
  • 1/2 teaspoon vanilla extract
  • 1 cup peanut butter
  • 1/2 cup M&Ms


  1. Preheat the oven to 375 degrees F.
  2. In a large bowl, whisk together the flour, baking soda, salt, and quick cooking oats.  Set the dry ingredients aside.
  3. In a large bowl, cream together the butter and sugar.
  4. Beat in the egg, vanilla extract, and peanut butter until it’s all combined and set the wet ingredients aside.
  5. Gradually mix the dry ingredients into the wet ingredients.
  6. Gently mix in the M&Ms.
  7. Scoop about 1 and 1/2 tablespoons of dough into balls, and place about 2 inches apart on parchment paper or a silicon pad.
  8. Bake in the preheated oven for 8 to 10 minutes or until the edges of the cookies are slightly brown.  The center of the cookies may look under baked but they will set as they cool.  Let the cookies rest on the baking sheet for about 3 minutes and then move them to a wire rack to cool completely.

Store the cookies in an air tight container on the counter or in a zip lock bag in the freezer.


Make sure you use quick cooking oats for this cookie recipe.  Quick cooking oats are mostly pre-cooked and are rolled thin or cut into small pieces, perfect for baking cookies, like these.  As opposed to rolled oats, which are thicker and hold their shape better in the cooking process for goodies like my Homemade Granola.


The oatmeal really kicks this cookie up a notch from just the standard issue peanut butter cookie.  Does oatmeal make this cookie healthy?     😉


Here enters the almighty sweet chocolate.  I had some Easter M&Ms in the house so I decided to use those.  Feel free to use chocolate chips if you have those handy instead.  I think next time I make these cookies I’ll need to add more M&Ms…I am a chocoholic after all.    😉


Everyone has their preference of whether they like a chewy or crunchy cookie.  I’m a big fan of chewy cookies.  These cookies are chewy on the inside and crunchy on the outside so you get the best of both worlds here.


Peanut butter, oatmeal, and chocolate are a classic combo and there is a reason for it.  It’s simply delicious.  🙂

  2. My husband and I LOVE cookies, too, and we are always looking for new amazing cookie recipes. These look awesome! Happy Friday to you too!

      Thanks! We never get tired of any cookie but I’ll admit that a new different recipe is always more fun. 🙂
